T at whom it may concern.-

Be it known that I, ABNER B. HUTGHINS, a citizen of the United States,residing in the borough of Manhattan, city, county, and State of NewYork, have invented certain new and useful Improvements in Oil-Stoves,of which the following is a specification.

My invention relates to oil-stoves, and more particularly to oil-stovesof the blue-flame IO type, and the invention isdirected moreparticularly to the burners in such stoves.

The invention will be fully described hereinafter, and thefeatures'ofnovelty pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a transverse Verticalsectional viewof one form of oil-stove embodying my invention. Fig. 2 isa fragmentary transverse sectional view of the wick, the wick-trough,the oil-pipe, and adjacent parts of the structure. Fig. 3 is a frontview, partly in section, of the stove represented in Fig. 1. Fig. 4 is adetail plan view, with parts broken away, of a modified form of cylinderconstruction. Fig. 5 is a central vertical sectional view of a modifiedform of burner construction. Fig. 6 is a detail top view of one of therings. Fig. 7 is a bottom view of the same. Fig. 8 is a transversesectional View of a series of the rings represented in Figs. 6 and 7.Fig. 9 is a fragmentary bottom view of the top ring of the outsidecylinder represented in Fig. 5. Fig. 10 is a traus verse sectional Viewof the same, together with some of the cooperating rings.

The burner may be made by constructing what I term the inner cylinder Aof a plurality of superposed rings B or segments a, Fig. 4., which arespaced apart by suitable meanssuch, for instance, as lugs bpro- 4o Videdon each of the rings or segments and adapted to maintain them spacedapart, so as to form narrow slots or openings 0 between each pair ofsuperposed rings or segments. These slots are intended to take the placeof 4; the openings in the ordinary sheet-metal cylinder heretofore usedand. permit the air .to pass from the interior of the cylinder A, formedby these rings or segments, to the outer portion thereof, where theignition of oil takes place. Suitable means are provided to maintain thesuperposed rings, sections, or segments in the operative position. Thus,

for instance, one such means consists in providing grooves ordepressions e in the face of each ring, into which the lugs 12 on theopposite face of the ring below is adapted to pass inorder to secure therings against lateral displacement with relation to one another and soas at the same time to provide the proper space or openings between thevarious rings for the passage of air from the interior of the cylinder Ato the outside thereof, as shown in Figs- 6, 7, and 8. Where segmentsare employed to make up thecylinder, each segment a is preferablyprovided with a plurality of lugs 19, and the superposed segments arepreferably arranged so as to break joint, as represented in Fig. 4 ofthe drawings, thus uniting all of the segments one to another to formthe cylinder. A defiector plate f is preferably provided at the lowerportion of the inner cylinderAto prevent a too-rapid admission of air tothe interior thereof. In certain instances I prefer to employ aninterior foraminous sheet-metal air-distributing cylinder 0 within theso called"inner cylinder A. This sheet-metal cylinder 0 assures theproper distribution of air to the cylinder A and may be made of sheetmetal without injurious effects, by reason of the fact that ignition orflame is outside of the cylinder A and does not attack thisair-distributing cylinder 0. Air passes between the deflector-plate fand the centrally-apertured plate g to the interior of the cylinder 0and passes out through the perforations h.

The plate'g prevents air from passing into the cylinder A except by wayof the perforations in the cylinder O.

The various segments or rings making up the inner cylinder A are securedtogether and to other portions of the burner by any suitable means,preferably by a plate D, whichv cure the parts in placeand by'whichneans the parts may be readily disconnected for the purpose of repair;

The plateD is preferably provided with an upturned flange it, which isperforatedor apertured, as indicated at Z. These perforations permit theflame to be deflectcd toward the center of the burner, as indicated bythe arrows, and thus provide a burner of greater efficiency than wouldbe the case where a mere ring of flame is produced.

At the lowermost portion of the inner cylinder A and at the outsidethereof I provide an annular trough E, which preferably supports a loosering-like asbestos wick F in place. This wick extends into the trough,to which oil may be conveyed by a suitable pipe on, and any desiredmeans, such as are indicated at G, are provided for regulating theamount of oil which flows to the trough from a suitable reservoir Hconnected to the stove.

Surrounding the so-called innercylinder A and the wick and concentrictherewith is a second cylinder 1, which may be made of foraminous sheetmetal, as shown in Figs. 1 and 3, because of the fact that this secondcylinder is not attacked by heat to such a degree as is the innercylinder A. However, in certain circumstances it may be consideredadvisable to make up this second cylinder in the same manner orsubstantially the same manner as the inner cylinder A, except for thefact that there will be no top plate upon the uppermost ring.

In Fig. 5 Ihave illustrated the second or outer cylinder J, which ismade up of a plurality of rings or segments. In this construction theseparate rings or segments a may be secured together by forming ears orlugs 0 upon the uppermost and lowermost rings and passing rods or boltspthrough these ears and through lugs formed on the flange q of the outerimperforate drum K, so as to maintain the entire series of segments orrings fixed with relation to one another and with relation to the drum.The space between the inner and outer so-called cylinders A and K or Aand J, as the case may be, is Where the ignition takes place, and theouter cylinder is surrounded by the drum K, so as to form an air-space00, whereby air may enter at the bottom and escape at the tap. The drumK is connected to the outer cylinder, and the two are adapted to beraised together, so as to give access to the trough to enable theoperator to ignite the burner. For this purpose I have shown a yoke L,the free ends of which are adapted to be seated in sockets r in the drumK and which moves in avertical direction in guideways s. A lever M ispivoted to the frame of the stove, as indicated at i, and the free endof this lever extends through a slotted plate a, in which a notch o isprovided to support the lever M, yoke L, drum K, and the cooperatingouter cylinder in the elevated position to give access to the wick toignite and extinguish the flame.

It is obvious that the burner construction may be employed in anoil-stoveof anysuitable or desired construction and that the essentialfeatures of my invention are directed to the burner construction itselfwithout relation to the character of the stove in which it is employed.

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. In an oil-stove, the combination of an inner cylinder made up of aplurality of superposed cast-iron rings of uniform size and shape havingair-passages between them, imperforate means for closing the top of saidcylinder, means for admitting air to the interior of said cylinder atthe lower end thereof, an outer cylinder having openings therein, whichouter cylinder surrounds and is concentric with the inner cylinder andan imperforate drum surrounding the outer cylinder and so spaced withrelation thereto as to provide an air-space between said drum and outercylinder.

2. A stove comprising a perforated outer cylinder and a perforated innercylinder one of which is formed of a plurality of superposed rings ofuniform size and shape suitably spaced apart and forming a combustion orflame chamber between them, a wicktrough located at the bottom of saidchamher, a perforated air-distributing cylinder located within the innercylinder, an imperforate top plate for closing the upper end of theannular space between the air-distribut- -ing cylinder and the innercylinder, and an imperforate bottom plate extending from the lower endof the air-distributing cylinder to the wick-trough.

3. A stove comprising a perforated outer cylinder, a perforated innercylinder spaced therefrom, one of said cylinders being formed of aplurality of superposed rings of uniform size and shape and suitablyspaced apart, means for forming a flame between the said cylinders, anair-distributing cylinder located within the inner cylinder, a base orframe for supporting said cylinders, a top plate engaging the innercylinder and the air-distributing cylinder, and a bolt extending fromsaid plate to the base through the central space surrounded by theair-distributing cylinder.

4. A stove comprising a perforated cylindrical structure composed of aplurality of superposed rings suitably spaced apart,1neans located atone end of the structure for form ing an annular flame around saidstructure, and an imperforate plate for closing the end of the centralspace surrounded by said structure, at the other end of the structure.

5. A perforated cylinder for stoves consisting of a series of superposedrings each of which has an annular groove on its lower surface and isprovided on its upper surface with lugs arranged to project into thegroove of the next ring above and to space adjacent rings so as to leavean air-passage between them.
